Why do patients with cardia cancer experience pain

Cardia cancer is a special type of gastric cancer, so experts remind everyone not to ignore cardia cancer. Pain is one of the common symptoms of cardia cancer. So, what is the cause of pain in cardia cancer ? In response to this question, let the experts give you a detailed introduction to the causes of pain in cardia cancer.

1. Causes of pain in cardiac cancer: pain caused by the growth of cardiac cancer

The growth of cardia cancer has a great impact on the body, which is very different from benign tumors. Benign tumors develop in an expansive manner, so the obstruction and tenderness to local tissues and organs are more obvious. Cardiac cancer mainly develops in an invasive manner, and its tissue cells are different from normal tissues in morphological structure, functional metabolism, biochemical changes and enzymology. It also invades adjacent tissues and organs, destroys tissue structure, and changes its function. The worse the differentiation, the faster the growth. The blood supply to the tumor is relatively reduced, and central necrosis, swelling, exudation and combined infection of the tumor are prone to occur. If the nerves and blood vessels in the area of ​​cardia cancer are involved, cancer pain may occur; if tumor cells invade nerves or tumors compress nerves, severe pain may occur; if tumor cells invade blood vessels, vascular blood supply disorders may occur and pain may occur. The growth of cardia cancer causes capsule expansion and compression, or rupture and bleeding stimulate the pleura and peritoneum to cause pain. Nasopharyngeal carcinoma invades the trigeminal nerve and causes headaches; liver cancer invades the liver capsule and causes severe pain in the liver area.

2. Fear aggravates the patient's pain

Cardiac cancer is a difficult disease to treat. Cancer pain is the most severe chronic pain. Cardiac cancer patients are very afraid of it. At the same time, patients will receive adverse stimulation throughout the course of the disease. The causes of cardiac cancer pain, such as harmful diagnosis, physical decline, loss of work and living ability, medical condition restrictions, misunderstanding and even discrimination from others and units, can all lead to psychological changes in patients, causing depression and anxiety, aggravating the deterioration of the whole body, and causing a vicious cycle. This leads to an increase in the brain's sensitivity to pain stimulation and a decrease in pain threshold, aggravating the patient's pain.

3. Pain caused by the spread of cardia cancer

Cardiac cancer can infiltrate adjacent tissues and organs at the primary site and cause pain in cardiac cancer because it can also metastasize (or spread) to other parts of the body other than the primary site through other pathways (such as the vascular system, lymphatic system, detached implants, etc.). If the tumor invades and compresses blood vessels, nerves, and organs, not only will the functions of the corresponding tissues and organs change, but pain will also occur. Cardiac cancer may even compress nerves and adjacent bone tissues and cause pathological fractures. Cancer cells invade viscera and blood vessels, causing arterial occlusion, venous bleeding, and visceral cavity obstruction, squeezing and stimulating the nerve receptors in the visceral capsule, chest, abdomen, and vascular wall, causing pain in the corresponding parts.

4. Substances produced by cancer cells cause pain

Some cardiac cancers produce hormone-like chemicals, metabolites of tumor cells, decomposition products of necrotic tissue, and toxins produced by secondary infections after reduced disease resistance, which can all activate and sensitize pressure receptors and chemical receptors, causing physiological and pathological changes in nerves and pain. In addition, the above factors also increase the body's consumption and cause fever, so that the patient eventually develops severe anemia, weight loss, metabolic disorders, and develops cachexia, which aggravates the pain. This is one of the causes of pain in cardiac cancer.

The above is the introduction of why patients with cardia cancer experience pain. It is for your reference only. I believe that everyone has understood the causes of pain in cardia cancer. I hope everyone can do a good job in preventing cardia cancer. If you still have questions about the causes of pain in cardia cancer, please consult online experts!
